To reduce this the tube may be supported internally and or externally to preserve the cross section. One side effect of bending the workpiece is the wall thickness changes the wall along the inner radius of the tube becomes thicker and the outer wall becomes thinner. When calculating a two plane bend, one must know the bend angle and rotation (dihedral angle). A 2D tube has the openings on the same plane a 3D has openings on different planes.ДЄ two plane bend or compound bend is defined as a compound bend that has a bend in the plan view and a bend in the elevation. More complex geometries include multiple two-dimensional (2D) bends and three-dimensional (3D) bends.

Common simple bends consist of forming elbows, which are bends, and U-bends, which are 180В° bends. The very first machine went into service in 1996 and is still in production.ДЄ tube can be bent in multiple directions and angles.

The first all-electric tube bending machine was invented in 1995 by UK company Unison Ltd.Д«ased in Scarborough, North Yorkshire, Unison developed bending machines with 20mm, 40mm and 65mm tube capacity. Other factors involved in the bending process are the wall thickness, tooling and lubricants needed by the pipe and tube bender to best shape the material, and the different ways the tube may be used (tube, pipe wires). However, square and rectangular tubes and pipes may also be bent to meet job specifications. Generally, round stock is used in tube bending. Freeform-bending processes, like three-roll-pushbending, shape the workpiece kinematically, thus the bending contour is not dependent on the tool geometry. These processes can be used to form complex shapes out of different types of ductile metal tubing. Straight tube stock can be formed using a bending machine to create a variety of single or multiple bends and to shape the piece into the desired form. Tube bending may be form-bound or use freeform-bending procedures, and it may use heat supported or cold forming procedures.ДЇorm bound bending procedures like вЂњpress bendingвЂќ or вЂњrotary draw bendingвЂќ are used to form the work piece into the shape of a die. Chaffee Memorial Blvd., Wyoming, MI 49548, 61, fax: 61, bending is any metal forming processes used to permanently form pipes or tubing. Schwarze-Robitec America Inc., 3566 Roger B. No bolts are required to fasten the freely stored bend former to the turntable, which increases repeatability and process security. Tension bars are easily opened and closed for tool changing. Quick-Tool-Unlock ensures faster refitting times with a rapid clamping system for the bend former. This reduces production time by 20% to 40% depending on component and tube geometry. A vertically adjustable pressure die moves to the individual levels in sync with the tube.ДЇor each bending sequence, the NxG control system assesses the interaction between all axes, operating them simultaneously and preparing the next sequences. Despite its multistack bending tool, the machine is able to cut tubes as well because of its extended vertical transport carriage. Depending on tube system, the controls increase output up to 50% due to simultaneous operation of the axes.Д«y combining the bending and cutting processes for 3-in-diameter tubes, the CNC 80 E TB MR shortens turnover times and reduces waste by up to a 90%. Because the electric controls are integrated into the machineвЂ™s body, the tube bender doesnвЂ™t require an external control cabinet and can therefore be easily moved around the production area if necessary. Thanks to intelligent scanners and a slim machine bonnet, the machine can be operated without safety fences.

Like all Schwarze-Robitec machines, the bending table and bend former can be operated independently, simplifying the entire process. Tubes with complex geometries can thus be bent in one step. ItвЂ™s available in left/right bending versions and a version with a bending head that rotates 180 degrees. The fully electric machine bends steel tubes up to 1 in in diameter and wall thicknesses of 0.08 in as well as stainless steel tubes up to 0.8 in in diameter and wall thicknesses of 0.06 in.
